Question

Perform the requested operation or operations.

f(x) = 4x + 6, g(x) = 5x2

Find (f + g)(x).

Answer 1

first off, you'll need to distribute the "x" in equation:
(f + g)(x)

then use substitution, which I can show you once you're that far ^_^

Answer 2

so f(x) + g(x) ? @DemolisionWolf

Answer 3

bingo!
now substitute in what f(x) stands for and what g(x) stands for into that f(x) + g(x) equation you got

Answer 4

would that be (4x+6)+(5x^2) ?

Answer 5

@DemolisionWolf

Answer 6

right again!
now the parenthsies can go away becuase the only thing separating them is a "+" so this:
(4x+6)+(5x^2)
becomes
4x+6+5x^2
can you do the rest?

Answer 7

5x^2+4x+6? @DemolisionWolf

Answer 8

bingo!
now as far as I can tell, you just needed to do the operations, not solve for x.
or do you have to solve for x?

Answer 9

all it says is order of operations, thank you!

Answer 10

^_^
good work!
